Glycerol and triethyl citrate plasticizer effects on
The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
Effect of plasticizers on the mechanical and thermomechanical
The impact of thermo-compression molding parameters and the effect of plasticizers on mechanical, optical, water resistance and morphological properties of the films were studied. Pectin thermoplastic formulations were significantly affected by changing the plasticizer, its quantity and the time of compression.
Effects of Plasticizers on Mechanical Properties, Oxygen
Tensile strength and elastic modulus of films were decreased when adding plasticizers, whereas elongation at break were increased. Therefore, it caused an increase in oxygen permeability of...
Effect of Different Plasticizers on the Mechanical and Surface
Films were prepared by casting alkaline solutions of gliadin, a major wheat storage protein fraction. Their compositions and mechanical and surface properties were analyzed. Five polyols of the ethylene glycol series and glycerol were compared as plasticizers. The plasticized film-forming solutions exhibited viscosities almost independent of shear rate. Glycerol-containing protein solutions
Influence of plasticizers on the properties of NBR materials
Some substances used as plasticizers have a health risk or result from insufficient material properties. Therefore, the research is permanently going on to find alternatives. A further point is...
- Do plasticizers soften thermomechanical properties?
- The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
- Does plasticizer affect the disintegration of pullulan films?
- The hydrophilic nature of pullulan seems to have dominated over the plasticizer effects in concentrations range studied, facilitating rapid disintegration of films. Thus, this study indicates that plasticizer can only influence the flexibility and mechanical properties of pullulan films but not their disintegration.
- Which plasticizer is used to plasticize PVA resin with a DP of 2400?
- In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400. Both PVA/plasticizer films possess excellent optical transmittance and mechanical ductility, whereas the films blended with DEA exhibit higher strength than the PVA/GLY films.
- What are the effects of plasticizer in film production?
- For instance, inadequate or excessive use of plasticizer in films may lead to improper film formation, partial or full phase separation eventually leading to poor or unacceptable quality. In addition, disintegration time of ODFs is important, as it may significantly affect drug release and thereafter absorption and bioavailability.
- Do plasticizers affect mechanical properties?
- For food packaging applications, mechanical properties are of vital importance, so it is highly important to have general knowledge about the effect of plasticizers on mechanical properties, as well as on physical, thermal, and barrier properties, to be able to develop successful packaging materials.
- Do plasticizers increase tensile strength and elongation at break?
- HPMC/BW composite films incorporated with 2% of plasticizers formed films with the best characteristics among three tested concentration. Tensile strength and elastic modulus of films were decreased when adding plasticizers, whereas elongation at break were increased.
